Mechanism of tremolite carbonation

Applied Geochemistry, 2011
Abstract The direct aqueous carbonation of fibrous tremolite was investigated by TEM, powder XRD, and FT-IR to elucidate the transformation mechanism of tremolite into calcite. The TEM study revealed that tremolite dissolves along the weak cleavage on (1 0 0) and (1 1 0) and the cleavage fragment fibers. The preferential release of Ca, relative to Si

Health Effects of Tremolite

Annals of the New York Academy of Sciences, 1991
Although tremolite asbestos has been well characterized since 1916, appreciation of its role in disease induction is relatively recent. It has always been understood that the morphology of tremolite is complex, and part of the slowness in recognizing it as a hazard has been definitional in nature.

Chrysotile, Tremolite, and Malignant Mesothelioma in Man

Chest, 1988
The question of whether chrysotile asbestos ever causes mesothelioma in man has become a major public and occupational health issue. Review of the literature suggests that only 53 acceptable cases of chrysotile-induced mesothelioma have ever been reported; of these, 41 cases have occurred in individuals exposed to chrysotile mine dust, all of it ...

Tremolite-richterite amphiboles

The American Mineralogist, 1993
The substitution NaNa□-1Ca-1, which fills the A site, has been investigated in amphiboles close to the join tremolite-richterite. At 1123 K, compositions of amphiboles synthesized from bulk compositions on this binary are displaced towards magnesio-cummingtonite [Mg7Si8O22(OH)2], such that average compositions are better represented by the pseudobinary
